l,United States PatentO An object of the present invention is to provide a smoki ing pipe of the water reservoir type in which condensed liquid may be evacuated from the stem housing a rotatable pipe stem at the will of the user.

A further object of the present invention is to provide a smoking pipe of the water reservor type in which communication may be established between the stem housing a rotatable pipe stem and the water-containing body or between the stem housing and the atmosphere at' .the will of the user;

A still further object of the present invention is to provide a smoking pipe of the water reservoir type in which a visual external signal is provided for indicating the communication between the stem housing and v`the. water-containing body or the steml housingv and the atmosphere.

These and other objects and advantages of the present invention will be fully apparent from the following description when taken in connection with the annexed drawing, in which:

Figure 1 is an isometric view of the smoking pipe according to the present invention in assembled condition;

Figure 2 is an exploded isometric view of the assembly shown in Figure 1;

Figure 3 is a Sectional view, on an enlarged scale, taken on the line 3-3 of Figure 1, showing the rotatable pipe stem in one position with the stem in communication with the water-containing bowl;

Figure 4 is a view similar to Figure 3, showing the stem in another position in which the interior of the stem is connected in communication with the atmosphere; and

Figure 5 is a Sectional view taken on the line 5-5 of Figure 4.

Referring in greater detail to the drawing in which like numerals indicate like parts throughout the several views, the smoking pipe according to the present invention comprises an upstanding body 1-0' having an open top and a shallow pan 12 provided with a sealing flange 14 extending exteriorly therearound adjacent the perimeter thereof and positioned over the open top of said body 10. The sealing flange 14 rests upon the open top of the body 10 with the portion of the pan 12 below the flange 14 within the body 10.

The pan 12 is provided with a hole 16 in its mid-pon tion. A tobacco-receiving bowl 20 is positioned above and over the pan 12 and has a groove 22 extending ex` teriorly therearound inwardly of the underface of the bowl 20. The bowl 20 is positioned so that the groove is above the pan 12 with the portion adjacent the perin-` eter of the underface of the bowl 20 seating upon the flange 14 of the pan 12.

A vertically disposed smoke discharge tube 24 extends through the bottom of the bowl 20 and extends through the hole 16 in the pan 12 and has the upper end in com ice munication with the bowlv 20 and has the -portion ad jacent the lower end within the interior of the body V10.

A hollow open-ended tubular member 26 is positioned substantially at right angles to the body 10 and a hollow shank 28 having one end closed and the other end open is'fixedly positioned within the tubular member 26 so that the portion adjacent thel closed end is within the interior ofthe body 10 and-inwardly of and spaced from one end of the tubular member 26. The shank 28 has one endl closed by a plug 30.'which is provided with a bore extending inwardly from one end thereof.

An upstanding conduit 32 is positioned within the body 10 and has the lower end thereof connected through the portion of the shank 28 adjacent the closed end into and with the interior of the shank 28. The upper end of the conduit 32 extends into the groove 22 formed in the underside of the bowl 20. The pan 12 and the groove 22 form a chamber for the condensation of tobaccoV tars and water Vapor. The conduit 32 extends through. an aperture 18 formed in the pan 12 on one side of the hole 16, Figure 5, the aperture 18 being of a size larger than the conduit 32 and forming with the conduit a communicating passageway between the interior of the body 10 and the chamber formed between the pan 12 and the groove 22.

As shown in Figure 5,. the pan 12 is also provided with three other apertures o n the opposite side of the hole 16, said apertures being indicated by the numerals 19, 21 and' 23, and forming an egress for condensed water vapors from such chamber into the body 10.

A vertically disposed discharge plug 34 extends through the tubular member 26 and through the shank 28 and has one end in communication vwith the interior of the shank 28. The plug 34 is below and spaced from the lower end of the conduit 32. The lower end of the plug 34 is in communication with the atmosphere. The plug 34 has a narrow discharge orifice 36 extending from one end to the other. v

A horizontally disposed stem 38 extends through the open end of the shank 28 and is mounted in the shank 28 for rotation about the longitudinal axis of the stem 38. The stem 38 has a coaxial extension 40 which is solid and which has smoke ducts 43 therein transversely directed with respect to the smoke passage 37 provided in the stem 38. The extension 40 includes a second extension 41 which is smaller than the extension 40 and is axially offset therefrom. The portion of the second extension 41 adjacent the free end extends into the bore provided in the plug 30 and is adapted to seat and close either the opening in the upwardly-directed smoke duct by closing the lower end of the conduit 32 or the discharge orifice 36 in the downwardly-directed plug 34. When the stem 38 has been rotated in the direction to bring the second extension 41 into the position shown in Figure 3, the portion of the extension 41 adjacent the free end seats upon and closes the orifice 36 in the downwardly-directed plug 34 and establishes communication between the interior of the hollow shank 28 and the interior of the conduit 32. Upon rotation of the stem 38 in the opposite direction to bring the extension 41 in the position shown in Figure 4, the portion of the extension 41 adjacent the free end seats upon and closes the lower end of the conduit 32 and establishes communication between the interior of the hollow shank 28 and the atmosphere through the discharge plug 34.

A visual signal 42 is provided on the exterior of the stem 38 for indicating the position of the second extension 41 relative to the seating upon and closing of the lower end of the conduit 32 of the orifice 36 in the plug 34. In Figure 3, the signal 42 is uppermost indicatng that the smoking pipe is in the condition for smoking i 3 the orifice 36 closed and in Figure 4 the signal 42 is lowermost indicating that the passage from the bowl 20 to the pipe stem 38 is closed and the venting orifice 36 is open.

The solid extension 40 of the stem 38 is provided with fins 44, the fins serving to aid in the condensation of any vapors or tars which are not condensed above the pan 12.

Preferably, both the body 10 and the bowl 26 are provided with liners 46 and 48 (Fig. 3) although they may be omitted if desired.

The vertically disposed tube 24 is in two sections with an upper portion threadedly received through the bottom of the bowl 20 and threaded in the lower portion which, in turn, has its lower end threaded into a plug 5d provided in the bottom of the body 10.

The tube 24 has discharge openings 52 above the lower end thereof and connecting the interior of the bowl 20 with the interior of the body for the passage of smoke therethrough.

In use, the smoking pipe of the present invention normally has a charge of cooling water in the body 10 and smoke is drawn from the bowl 20 through the cooling 'water into the conduit 32 and thence to the pipe stem 38. When it is desired to jettison or discharge any accumulated condensed water vapors or tar vapors that may be within the hollow shank 28, it is only necessary to rotate the stem 38 to a position in which the signal 42 is lowermost as in Figure 4 and then with air blown through the stem 38 any accumulated moisture within the hollow. shank 28 is discharged through the plug 34. Upon return of the signal to its uppermost position, the pipe is again ready for continued smoking.

While only a preferred embodiment of the present invention has been shown and described, other embodiments are contemplated and numerous changes and modifications may be made therein without departing from the spirit of the invention as set forth in the appended claims.
